Functional Description Unipolar Type TLE 4905 (figure 3 and 4)
When a positive magnetic field is applied in the indicated direction (figure 3) and the
turn-on magnetic induction B_OP is exceeded, the output of the Hall-effect IC will conduct
(Operate Point). When the current is reduced, the output of the IC turns off (Release
Point; figure 4).
